Hydras and global key bindings

[jerrypnz]

1. I would like to have some key bindings that work in all modes (major or minor).

You can use pretty-hydra and bind it to a global key.

2. And I would like hydra not to show hint for the key binding.

Don't think you can hide the hint completely but you can set an idle delay, e.g.

(pretty-hydra-define test-hydra (:quit-key ("<escape>" "q") :idle 1.5)
  ("Eval"
   (("i" elpy-importmagic-fixup "Importmagic fixup")
    ("d" elpy-goto-definition "Goto definition"))))

You can use pretty-hydra and bind it to a global key.

I have bind my pretty-hydra to the global key this way:

(defun Pfedj/hydra-test ()
  (interactive)
  (funcall
   (pretty-hydra-define test-hydra (:quit-key ("<escape>" "q"))
  ("Eval"
   (("i" elpy-importmagic-fixup "Importmagic fixup")
    ("d" elpy-goto-definition "Goto definition"))))))

(global-set-key (kbd "M-<SPC>") 'Pfedj/hydra-test)

I would like to add heads to an already existing test-hydra:

(pretty-hydra-define+ test-hydra (:quit-key ("<escape>" "q") :idle 1.5)
  (;; these heads are added to the existing "Eval" column
   "Eval"
   (("r" transpose-frame "rotate")
    ("z" zone "zone out!"))
   ;; this is a new column, which gets added
   "Appearance"
   (("f" set-frame-font "font")
    ("t" load-theme "theme"))))

It doesn't work. How can I do it?

It doesn't work because every time Pfedj/hydra-test is called, your hydra is re-defined with pretty-hydra-define which blows away the existing one. You don't really need that wrapper function, just bind the hydra body to a key:

(pretty-hydra-define test-hydra (:quit-key ("<escape>" "q"))
  ("Eval"
   (("i" elpy-importmagic-fixup "Importmagic fixup")
    ("d" elpy-goto-definition "Goto definition"))))

(global-set-key (kbd "M-<SPC>") 'test-hydra/body)

I have lost postfix /body when I try to bind hydra with global-set-key as you describe. So it works. Thank you for you clarification.
